Based in Aberdeen Plexus has become the largest supplier of specialist jack-up exploration wellhead equipment with nearly 100% of the North Sea market, and a growing international reach including Brunei, China, Egypt, Malaysia, Russia and West Africa.

Ben is also a successful entrepreneur and received the accolade of Entrepreneur of the Year 2013 at Grant Thornton’s Quoted Company Awards.

Our unique POS-GRIP products are safer, more reliable and cost-effective, and technically superior to our competitors’ and it is thanks to the success of this technology, and future prospects in the important subsea sector that Plexus is confident that despite current oil price volatility the long term future is exceptionally bright..

Big picture - Why invest in Plexus Holdings

Plexus Holdings Snapshot


Plexus Ocean Systems Ltd. provides various products to the Oil and Gas industry utilising its patented POS-GRIP® Friction Grip Technology. Having already been used on hundreds of wells throughout the world, Plexus continue to develop the technology and its products range to provide solutions to the industry in areas where none were available or which needed to be improved.

POS-GRIP Technology was initially created as a method of supporting oil field tubulars with an externally activated radial friction grip.

Its first application in the oil and gas industry was through the introduction of an adjustable rental wellhead system for jack-up exploration drilling.

The benefits demonstrated by the POS-GRIP jack-up drilling system, used in conventional field applications, led to the development of proprietary, specialised high pressure and high temperature (HP/HT) HG Production Wellhead systems, which are key to the industry as it shifts to more extreme operational environments in response to increasing global demand for oil and gas products.

The operational and cost saving benefits delivered  by the original POS-GRIP standard pressure exploration jack-up drilling system led to the development of proprietary, specialised high pressure and high temperature (HP/HT) jack-up drilling systems as well as HG Production Wellhead systems, and Connectors

Our Technologies Division is the research and development arm of Plexus and, as such, assists in the design of new products as well as managing their development and testing.

From finite element analysis (FEA) to physical testing of components, Technologies designs and tests new products in compliance with, or in excess of, industry standards for release to the marketplace through the appropriate division.

As POS-GRIP® technology has continued to be developed, the range of potential applications has become apparent and our Technologies Division is developing and looking to develop upon that potential.

The Technologies division of Plexus works toward bespoke design concepts required by our clients and also looks at developing and improving designs and applications currently being utilised in the Oil and Gas Sector. The aim within Technologies is to design and test new products to current industry stands and beyond, therefore allowing Plexus equipment to achieve a greater potential.
